BlueCross BlueShield of Tennessee leaders announced Tuesday that their Gateway Building is the second to get LEED Gold Certification. 

“BlueCross is putting together a solid portfolio of green accomplishments, and adding the Gateway Building to that list is the culmination of a lot of hard work,” Dan Jacobson, vice president of properties and corporate services for BlueCross, said. “With Gateway we took a building over 40 years old and transformed it into a model of 21st-century efficiency, including adding solar panels, storm water filters and increased natural lighting.” 

During the renovation, crews used 96 percent of the exisitng walls, floors and roof. They also recycled 500 of the 782 tons of construction debris created during the project. 

The Gateway Building was originally built in 1965 and housed a Zayre’s department store. It also was once the home of WTVC and a Shoney’s.

BCBS moved offices into the building in 1993. It is the second largest LEED Gold Certified building in Chattanooga.

The Gateway renovations include:

—A newly installed, 198.24-kilowatt photovoltaic solar array, producing the equivalent of 40 percent of the building’s power.

—Improved air quality thanks to low-emission interior adhesives, sealants, carpets and paint.

—New heating and air units to provide better comfort and control.

—Increased opportunity for natural light in work areas and the use of induction lighting, manufactured locally, in the parking lots.

—State-of-the-art water control, including natural storm water filters that remove up to 100 percent of pollutants from runoff that would otherwise end up in the Tennessee River.

—More than 160 new trees and other landscaping improvements.

The BCBS Cameron Hill campus is also LEED Gold Certified
